Testing tooth fillings to stop leakage after root canal
Part of Mouth & dental clinical trials.
This trial tests how well different types of gutta percha (a rubber-like filling material) work with a special ceramic-based sealer to prevent leakage in teeth that have had root canal treatment. If you have an extracted tooth with a single mature root canal and no other problems, your tooth could help researchers find the best way to seal root canals.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You need to have an extracted human tooth to donate for this study.
- The tooth must have only one root canal and a fully grown root tip (mature apex).
- The tooth's root canal must not be completely blocked or hardened (calcified).
- The tooth should not have any root damage (resorption) seen on X-ray.
- The tooth should not have decay reaching the inner floor of the pulp chamber.
- The tooth should not have an open (immature) root tip.

This trial compares two types of root canal filling materials—bioceramic and calcium hydroxide—to see which one causes less pain after the procedure. If you have a tooth with a live but inflamed nerve, you may be able to join.
This study compares two types of fillings used after a root canal to see which one causes less pain afterward. If you have a tooth with severe, constant pain that needs a root canal, this trial may help find the best option for you.
This study compares two types of root canal filling materials—a resin-based sealer and a bioceramic sealer—to see which one causes less pain after the procedure. If you have a tooth with a painful, infected nerve (irreversible pulpitis), this trial may help determine which filler offers better comfort.
This trial compares two different filling materials used after root canal treatment on dead teeth. Researchers want to see which material causes less pain and swelling afterward.
This study looks at how well a bioceramic sealing material works for tooth root-canal treatment, including cases where previous treatment did not work. If you have certain types of tooth nerve inflammation or infection, you may be eligible to help compare outcomes and improve care.
This study is comparing two different materials used to fill the tooth after a root canal to see which one causes less pain afterward. If you need a root canal on a front tooth or a premolar and you don't have pain or swelling, this trial may help find the gentler option for you.
